Abstract: A package includes a frontside redistribution layer (RDL) structure, a semiconductor die on the frontside RDL structure, and a backside RDL structure on the semiconductor die including a first RDL, and a backside connector extending from a distal side of the first RDL and including a tapered portion having a width that decreases in a direction away from the first RDL, wherein the tapered portion includes a contact surface at an end of the tapered portion. A method of forming the package may include forming the backside redistribution layer (RDL) structure, attaching a semiconductor die to the backside RDL structure, forming an encapsulation layer around the semiconductor die on the backside RDL structure, and forming a frontside RDL structure on the semiconductor die and the encapsulation layer.

Abstract: A semiconductor package includes a base comprising a top surface and a bottom surface that is opposite to the top surface; a first semiconductor chip mounted on the top surface of the base in a flip-chip manner; a second semiconductor chip stacked on the first semiconductor chip and electrically coupled to the base by wire bonding; an in-package heat dissipating element comprising a dummy silicon die adhered onto the second semiconductor chip by using a high-thermal conductive die attach film; and a molding compound encapsulating the first semiconductor die, the second semiconductor die, and the in-package heat dissipating element.

Abstract: A steering device for a skateboard has a front seat mounted with a pair of front rollers. The front seat has an upwardly extending cylinder. A receiving hole is defined in a top surface of the cylinder. The receiving hole receives a sphere inside. The sphere is connected to a shaft. The steering device enables the skateboard to be turned agilely, and is able to be adjusted to suit riders of different sizes.

Abstract: A shock absorbing and slip resistant pad made of a foam material that has a resilient texture and a sufficient depth to absorb shock. The pad has a slip resistant surface and an engaging surface. The slip-resistant surface has sand evenly distributed therealong to form a rough surface for slip resistance. The engaging surface has an adhesive substance applied thereon to adhere the pad to the skateboard. A pattern is stenciled and color printed on the slip resistant surface for a decorative or a commercial effect.
